System Operation
System Operation Notes
The fresh water production of the Aqua Mini 170, 350, 550, & 750 depends on six factors:
• Feed Water Temperature
• Feed Water Salinity
• Feed Water Flow Rate
• Operating Pressure
• Characteristics of the individual R.O. Membrane Element
• Condition of the individual R.O. Membrane Element
Feed water temperature and salinity vary depending upon location of operation.
Feed water flow is fixed on the Aqua Mini 170 at .5 gallon per minute / 1.89 liters per minute; and on the Aqua Mini
350 at 1.5 gallons per minute / 5.68 liters per minute; Aqua Mini 550/750 at 3.5 gallon per minute / 13.25 liters per
minuteby design.
The only operator adjustment that remains is the operating pressure, which is adjusted at startup by the operator.
There are two parameters, which are controlled by this single operator adjustment: Operating Pressure and resulting
Product Water Flow.
The Operating Pressure is adjusted upward until the Aqua Mini 170 system produces 7 gallons per hour / 26.8
liters per hour; the Aqua Mini 350 System produces 14.6 gallons per hour / 55.2 liters per hour; Aqua Mini 550
System produces 23 gallons per hour / 87 liters per hour; Aqua Mini 750 System produces 31.25 gallons per hour
/ 118.3 liters per hour However, the maximum Operating Pressure allowed is 900 psi. Do not exceed 900 psi even
though the system does not produce the specified amount of product water. The system automatically shuts down
if the maximum Operating Pressure exceeds 950 psi.
External factors, such as Feed Water Temperature, Feed Water Salinity, or condition of the R.O. Membrane
Element may cause the system to produce less than specified even though the Operating Pressure is at 900 psi.
Operation Cautions
Open all valves on the piping or hoses leading to and from the system.
Check the Oil level in the High Pressure Pump.
Check for any abnormalities such as leaks, damaged hoses, wires, and etc.
Startup Procedure
1. Open the Cock Valve [2] fully.
2. Switch the electrical power to the system on at the circuit breaker. The “POWER” lamp on the system Touch
Pad will illuminate.
3. Ensure that the back-pressure regulator valve [17] is fully open (counterclockwise). This is not required and is
commonly skipped on systems equipped with a Remote Control. Performing this step reduces wear and tear
on the mechanical and electrical components.
4. Press the “Start” switch. This initiates the automatic start sequence. The automatic start sequence begins with
the booster pump starting immediately and the high-pressure pump following after a brief delay.
